vALvE-GRINDER.

To all lwhom z't may concern:

Be it known that I, JAMES J. GORMAN, a

i citizen of the United States, residing at Dugeneral character which may be appliedrango, in the 'county of La Plata and State i of Colorado, have invented certain new and useful Improvements in Valve-Grinders, of which the following is a specification, refer! ence being had to the accompanying drawlngs. l

. Thisinvention relates to certain improvements in valve grinders and has relation more particularly to a device of this general character especially designed and adapted for use in connection with water faucets; and it is an object of the invention to provide a novel and improveddevice of this with convenience and facility and wherein the grinding disk or member is automati-- cally maintained in requisite engagement with the valve seat to be ground through the medium of an expansible member interposed between said disk or member and the ycapy of the faucet.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved valve grinder whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advanta-`v geous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

vIn -order that my 'invention maybe the better understood, I will now proceed to ldescribe the same with reference-to the ac ,companying drawings, wherein- 1 Figure 1 is a View partly in elevationl and partly in section illustrating a grinding tool constructed in accordance with an, embodiment of my invention and in applied posi tion -Fig. 2 is an outer .face view of the grind? ing disk or member as herein embodied; and Fig. 3 is an outer face view of the polish-V ing disk or member as herein` disclosed.

As disclosed in the accompanying drawings, F denotes a faucet provided with the internal valve seat S .and with the remov-l Specication of Letters Patent.

able cap C, all of which are embodied in the structure of the faucet proper. To grind the valve seat S it 4will be understood that the conventional stem and valve is removed together with the cap C.

The cap C' is then slipped over the elon gated shaft or stem l of my improved grinding tool. One end of thestem or shaft 1 is provided with the hand grasp 2 herein disclosed as of a wheel'type whereby the requisite rotation may be imparted to theV the substantially radially disposed cutting` shoulders 6 whereby it will'be perceived that when said member or disk 5 is in contact with the valve seat S and movement im- 4 parted to the shaft lor stem 1 in one direction, thevalve seat S will be planed or cut to a smooth and even substantially concave surface.

Before vthe memberorv disk f5 is engaged' with the extension 3 the expansible'men'i'ber 7 is slipped upon the stem or shaft 1, said expansible member being herein disclosed as a conventional coil spring encircling the shaft or stem. The. member 7 is of such' a length as to be placed under compression or V tension when the cap C is operatively enaged with the bonnetv 8 of the faucet. When -'t e member or disk 5 is in appliedposition the. member 7 -is inlcontacti-with the inner face orA surface thereof, whereby said disk vor member 5 is constantly urged toward the valve seat. S and maintained in requisite 'contact therewith.

Afterjthe seat Shas been properly planed or cut it is preferred that the disk or member' 5 be removed andthe second disk or member 9 substituted therefor. IThis mem` ber '9 is .provided with a plane or smooth beveled surface 10 which, when properly operated relative to the seat S, serves to smooth and polish the same. The member or disk 9 may be employed either with or Without a fine abrasive material. f

After the valve seat S has been ,properly ground it will be at once self-evident that the stem or shaft 1 and its concomitant parts may be readily and conveniently removed and the valve and valve stem of the faucet be readily replaced. l

From the foregoing description, it is thought to be obvious that a valve grinder constructed in accordance With my invention is of an extremely simple and comparatively inexpensive nature and is particularly o Well adapted for use by reason of the convenience and facilityvvith Which'it maybe assembled, and it Will also be obvious that my invention is susceptible of some change and modification Without material departure 'from the principles and spirit thereof and for this reason I do not Wish to be understood as limiting myself to the precise arrangement and formation of the' -several parts herein shown in carrying out my i11- detachably engaged with the end portion of the shaft Within the faucet, the outer faces of said disk being provided with an annular beveled surface engageable With the internal` valve seat for grinding Athe same, and a spiral spring surrounding the shaft and contacting with the grinding disk, said spring being of such a length as to contact With the 'under faces of`the cap of the faucet for placing said spring under compression when the cap is engaged with the faucet, the outer end of the shaft being provided with 'a hand grasp for rotating the same.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses.
